WINDSHIELD-WNIPER FOR VEHICLES.

Application filed July 29, 1918. Serial N! 247,129.

To all whom it may co /town:

Be it known that I, 7 JOHN NV. CAIN, a

citizen of the United States, and a resident of Chicago, in the county of Cook and State v of Illinois, have invented certain new and useful Improvements in a Windshield Wiper for Vehicles, of which the following is a specification.

This invention relates to wipers which are primarily designed for and adapted to be attached to wind shields of automobiles, for

the purpose of being manually operated to clean the glass of said wind shield, when.

mud, dirt, snowor water is deposited thereon. And the objects of the invention areto obtain a device of the kind named wluch 1s attachable to the windshield of a touring body, limousine body or a'truck; to obtain a device easily operable, not liable to get out of order or break, and readily understood by chauffeurs and others who drive automobiles.

Additional objects are disclosed the specification and drawing. p 7

The manner in which I am able to attach the device either to a touring body where the wind shield is'independent of the top and sides of the car, to alimousine where the windshield. is built into the body of the car, or to a truck where therwind shield is inclosed in a wooden frame somewhat similar to a limousine body, is by making what I term reversible clamp members and track holders which I hereinafter definitely describe.

I have illustrated a wiper embodying my invention in the drawing accompanying and forming a part hereof. in which,

Figure 1, illustrates in vertical section a small part of the wind shield of a touring body car, and a device embodying this invention mounted thereon, with the track of the device back of the wind shield and the wi er in front thereof. I

ig. 2, a top plan view of the several members which are illustrated in Fig. 1.

Fig. 3, a front of a sliding member forming an element of the device, and

ig. 4, a like view as Fig. 1, with the device embodying the invention attached to the frame of the wind shield of 'a truck, and having the track and wiper in front of the shield.

Fig. 5 is a diagrammatic view illustrating the attachment to a wind shield of the modification which is illustrated in Fig. 4.

Fig. 6 is a perspective of a device embodying the invention.

Specification of Letters Patent. Patented 17, 1921;

' A reference character applied to a given part indicates said part throughout the several figures of the drawlng, wherever the same appears.

X, represents the glass of a wind shield,

and Y, the frame thereof.-

A, represents a clamp of which aplurality are used, respectlvely consisting of members a, a, the bolt B and nut C. Member ais provided with a lug D, which is illustrated as integral therewith. E represents ,a rod.

having parallel sides 6 e and the sides 6 6 The side 0 of rod E, is brought into cohtact with the end of lug D and said rod 1s rigidly secured to said end a. screw, F), which is indicated in Fig. 1. .G, represents a sliding block which is providedwlith:

a groove extendinglongitudinally therethrough which corresponds with the rod E,

sothat said block may be andis slidably. mounted on the rod E, said rod thereby forming a track for said block. Thegroove in block G, preferably has the sides thereof which come 1n contact with faces e, eian'dgel f ine w h e abafimee i e, as 1s lndicated at 9, Fig. Th'ewidthlof the w (9 f. h sr v n bl 1 ts-show aF g- 3.,.an thiSQPsni-ng is ss rclently wide to permit the lug D reenter and pass through said groove, thereby allowing the sliding block G to pass by said lug. This construction permits theclamps to be'placed at any point, endwise, on the'wind shield frame, and allows the sliding block to be moved the entire length of the track and wind shield. H, Figs. 1, 2, 3, and H, Fig. 5, represent handles, by means of which the sliding block G, in said Figs. 1, 2, 3, and G in Figs. 4 and 5 are moved on-tracks E, E,

which form the runways for said blocks. I

I, Flgs. 1, 2 and 6, represents amember which is provided with slot I and 1s rigidly secured to block G, as by the bolts or rivets i, 2'. Member I is preferably of spring metal. I represents a member which is secured at one of its ends to one face of block i Gr( as by rivet h, Fig. 4, or handle H, Fig.

6), and at its other end :yieldingly presses against the edge of wiper L. J representsa vertical rod which is'illustrated inFig's.

1, 2 and 6, as firmly securedat one end of member I, by extending it throughslot I and turning nut Kdown thereonto. J represents a vertical rod secured tothe under side of block G, Figs. 4 and 6, and in Fig. 1 as secured to block G, by extending it into said blocks.

L, Fig. 1, represents a wiper comprising the flexible scraper 1, which contacts with the glass X ofthe wind shield, and the body which extends around the rod J. M represents a slot in the portion of Wiper L which is so mounted on the rod J, and m a pin in said slot, said pin being driven into said rod. The swing or rocking of the wiper on said rod is limited by said pin and slot.

In Fig. 4 the member I, (being of resilient material as in Figs. 1 and 2), is secured to block G, (handle H being removed from said block), as by the rivet h; and N indicates, (Figs. 4 and 5), a strap or cable,

' which also is secured to said block, as by said rivet 72 In Fig. 4, the track E and the wiper L are on the same side of the wind shield, and the cable N extends around pulleys n, n, which are set in frame Y, (as

' indicated in the diagram, Fig. 5), said frame construction.

being of Wood and built above and on the sides of the wind shield, as is usual in truck To wipe a window glass of a wind shield 7 it is simply necessary to grasp handle H,

gllustrated in Figs. 1, 2 and 6), or handle (Fig. 5), and move the sliding blocks on the tracks which are provided therefor, as hereinbefore described.

In the constructions illustrated the membersI, and I being of resilient material, hold the wipers, (L, L), against the glass 4 of the wind shield substantially the entire length of the flexible scrapers thereof.

The slot I, Figs. 1 and 2, in member I,

. permits adjustment of rod J to and from the glass X, before setting nut K down on said member.

I claim 1. In a wiper for wind shields, in combination, clamps adapted to grip a wind track to one side of said frame, a member 'on said slidable block extending over said frame to the other side thereof, a rod secured to the end of said member, and a wiper mountedon said rod. 1 1

2. In a" wiper for wind shields, in combination, clamps adapted to grip a wind shield frame, projecting lugs on each of said clamps, atrack, means to secure said track to said lugs with one of the sides of said track contacting with said lugs, ablock provided with an undercut groove thereincorresponding in cross section wit-hthe cross section of said track, and slidably mounted thereon, the open side of said groove being adapted to pass said lugs, and said lugs arranged to position said track to one side of said frame, vertical rods, wipers thereon and means to secure said rods to said block.
